Understand and ask your lady what she likes - communicate, don't just assume what worked for an ex (who might have been faking anyways) will work for everyone else you ever meet or sleep with ....

Make sex fun - its not just an act (although sometimes it is, and there can be massively intensive quick-f*cks), blokes have a tendancy to get paranoid about their performance - and pissed off if they don't acheive what is in their minds .... your mind should be used to understand your partner not focus on yer ego...

Bring other stuff to the game - there is always a place for toys, lotions and potions ... but again, don't just bring yer girl home and launch on her with a 14" vibrator (or even a clit-bullet) until you have a level of trust, or are too pissed to care - orgasm requires relaxation....

Anticipation - build some up. I started sending my missus naughty texts this morning, and I KNOW I am having fun tonight - and so does she - the anticipation can be as much part of foreplay as physical contact.....

OH - and remember a womans orgasm can go on for a looooooong time - don't stop at the first sign of chest blushing and vaginal clamping.... change the stimulation ... elongate the experience .... maybe you will find the key to multiple orgasms ....
